About

The Certificate Chain Graph visualizes your SSL certificate chain as an interactive graph, showing the relationship between your leaf certificate, intermediate certificates, and root CA. Each node displays key certificate details including subject, issuer, validity dates, key type, and signature algorithm.

This visual representation makes it easy to understand complex certificate chains, identify unnecessary intermediates, and verify the chain structure follows best practices. The graph highlights potential issues like expired certificates, weak signature algorithms, or unusual chain paths that might not be obvious from text-based analysis.

How to Use

1Enter the domain name you want to visualize
2Click "Generate Graph" to build the certificate chain visualization
3Explore the interactive graph by hovering over nodes for certificate details
4Identify any chain issues highlighted in the visualization

Use Cases

•Chain Understanding: Visualize complex certificate chains to understand how trust flows from your certificate to the root CA
•Issue Identification: Quickly spot expired intermediates, unnecessary certificates, or unusual chain paths in the visualization
•Documentation: Generate visual chain diagrams for architecture documentation and security reviews
•Training:** Use the visual representation to explain certificate chains to team members who are less familiar with TLS

•Presentation:** Create clear, visual chain diagrams for management presentations and security briefings

Tips & Best Practices

•Use the graph view alongside the text-based chain validator for comprehensive analysis

•Export graph images for inclusion in documentation and presentations

•Compare chain graphs before and after CA migrations to verify the chain structure changed as expected

•Pay special attention to the number of intermediates — shorter chains are generally better

Frequently Asked Questions

The graph shows each certificate in your chain as a connected node: your leaf certificate at the bottom, intermediate certificates in the middle, and the root CA at the top. Each node displays the certificate subject, issuer, validity dates, key type, and signature algorithm. Connections show the signing relationship between certificates.

Chain length depends on the CA's hierarchy structure. Some CAs use a single intermediate, while others use multiple intermediates for different certificate types or geographic regions. Shorter chains (2-3 certificates) are generally preferred for performance, but the optimal length depends on your CA's infrastructure.

Yes, the graph can be exported as PNG (for presentations), SVG (for scalable documentation), or PDF (for formal records). The export includes all certificate details visible in the graph and can be customized to show different levels of detail.
